the documentation suggests to bind an own implementation of
IResourceDescription.Manager in order to limit the exported objects in a
certain resource.
The javadoc of DefaultResourceDescriptionManager however says that
customisation should be done by implementing a custom
IDefaultResourceDescriptionStrategy.

Is there a example somewhere demonstrating how this looks like in practice?
In my use case I want only a certain type being exported, all other named
elements should only be visible within the local resource.
